Cornus

Cornus is an ancient city-state of Sardinia, founded in the last quarter of the sixth century BC His remains are located near the town of Cuglieri, in the province of Oristano. The city consisted of an acropolis (it's possible to see the remains of the walls) on the hill of Corchinas and craft districts and homes in low-lying areas. The city is mentioned (Kornos) by the geographer Ptolemy (second century) in the interior of the island and is reported in the Itinerary Antonino (Cornos) halfway between Bosa and Tharros. Livy speaks of it as the capital of nuragici the time of the anti-Roman revolt Ampsicora in 215 BC, in which was conquered by Titus Manlius. Became a municipality in the Flavian period or Trajan and was a colony in the third century. In the town had to exist, on the hill of Corchinas, a public area, perhaps the forum, from which come some honorary inscriptions. Also visible are the remains of a thermal plant in listatum handiwork, probably restored under Gratian, Valentinian and Theodosius (379-383). The remains of the basilica Boniface, bishop of Sanaphar or Sanafer (identified by some scholars with the Diocese of Cornus [6]), with 466 other bishops, including the Sardinians Lucifer Kalaris, Martiniano of Trajan's Forum, Vitale of sulci and Felix Turris, participated in 484 at the Council of Carthage, which was organized by Huneric, King of the Vandals, with the intent to convert Catholics to Arianism. In late antiquity, not far from the town (village of S'Archittu) arose the Christian complex of Columbaris, with a vast cemetery that returned several sarcophagi and a first building a basilica in funerary, preceded by a baptistery (III -IV century). Two other churches were built in the fifth-sixth century, with other facilities. The first settlement was abandoned after the eighth century.
